Description

【技術分野】
【０００１】
本発明は、特にひと巻きの紙またはボール紙である、ひと巻きの物質の切返し装置に関し、該装置は、横断刃が取り付けられた２つのブレードドラムからなる切返し手段を設け、さらに切返し手段から下流に位置し、ブレーキローラーを備えるブレーキ手段を有するシート輸送手段を設けることを特徴とする。
【背景技術】
【０００２】
切返し装置は、個々のシートを生成するためにひと巻きの紙またはボール紙を切返し、シート輸送手段を有するように周知であるスタック上に続いて配置され、切返し手段から下流に位置し、ブレーキローラーを備えるブレーキ手段を有する。シートにブレーキが掛けられた場合、まだブレーキが掛けられていない続くシートの先端は、ブレーキが掛けられたシートの後部端上を摺動する。これは、積層手段で続いて積層される、オーバーラップするシートの流れを成す。前述の一般的な型式の切返し手段は、ドイツ国特許第１９９４５１１４に記載されている。
【０００３】
周知のブレーキ手段を用いて、ブレーキローラーが導く際にシートを下方にプレスする場合に、高速で流れるシートはブレーキが掛けられる。したがって、すでにブレーキが掛けられて、さらに遅いシートとなる。ブレーキ段階での２つのシート間の前述の相対的な移動により、紙またはボール紙の遅いシートが繊細なタイプである場合、マーキングが表面に成される。
【発明の開示】
【発明が解決しようとする課題】
【０００４】
したがって、本発明は、たとえ紙またはボール紙が繊細なタイプの場合でもシート上のマーキングを回避するような手法の一般的なタイプの切返し装置の改善を目的とする。
【課題を解決するための手段】
【０００５】
この目的は、ブレーキローラーが、弾性物質からなる放射状に突出するラメラが周囲に沿って互いに間隔を置いて付加される円筒状の基部要素から構成されることで達成される。前述のラメラは、基部要素に共軸である円筒状の包絡面で停止する。
【０００６】
放射状に突出するラメラを備えるブレーキローラーの形態により、シートは、シートの運動エネルギーがラメラに多大に移動してブレーキが掛けられる。弾性のラメラは、後ろに向かって偏向して、曲がる。それによって、偏向距離はシートのブレーキ距離である。この段階において、ラメラに対するシートをプレスする結果として、ブレーキローラーの有効な周辺の速度は、より遅いシートの伝達速度に対してほぼ完全に一致する。より速いシートが事実上ブレーキを掛けられた後でのみ、先行するシートに対してプレスされる。
【０００７】
従属項は、特に有用であるために好ましい本発明によるブレーキローラーの実施態様を含む。
【０００８】
添付図は、簡素な手法で描写された実施態様を参照して本発明を説明する役割をする。
【発明を実施するための最良の形態】
【０００９】
図１の一般的な図に示される装置は、連続的に供給されたひと巻き１から紙またはボール紙のシートを作る役目をする。ひと巻き／シートの移動方向（図では左から右）において、続く構成部分は連続的に配置される。
【００１０】
ひと巻き１の端部が切断され、任意にひと巻き１が６つの個々ひと巻きに分割される、縦に切断する手段２と、切断手段３と、切返し中に作成されたシートによるシート輸送手段４とが引き継がれてブレーキを掛けられ、それによって、オーバーラップするシートの流れが形成され、シートがパレットに基づくスタック６上に置かれる、積層手段が形成される。
【００１１】
周知の手法において、切返し手段３は、通常は、シートが通り抜けてひと巻き１が切断される手段によって１つの横断刃が取り付けられた一方がもう一方の上に配置された２つのブレードドラム８、９からなる。
【００１２】
シートの輸送手段４は、切返し手段３の背後に直接的に位置し、図２の拡大図で示される。シートの輸送手段は、切り返しによって生成されたひと巻きの始まりを引き継ぎ、かつ２枚のシート間のギャップを作成するために切返しによって作られたシートの一層の輸送を加速するために切り返し中にぴんと張ったひと巻きを保持し、かつ減速させられた輸送速度で積層手段５に供給されるシートをオーバーラップする流れを形成するようにシートにブレーキをかける要素を含む。
【００１３】
シートの輸送手段４は、上部のキャッチローラー１２と関連する速い下部のコンベアベルト１３で開始する。キャッチローラー１２は、同時に個々の並列のベルトから構成され、入って来るひと巻き１の速度より高速で駆動される、急速回転の上部のコンベアベルト１４の入り口側の偏向ローラーである。キャッチローラー１２と共に、下部のコンベアベルト１３は、入って来るひと巻きの開始が引き継がれてニップ（nip）を形成する。コンベアベルト１３は、上部のコンベアバルト１４の上昇速度で駆動される。したがって、切返しによって生成されたシートは、さらに増大した速度で輸送される。
【００１４】
シートロック１５から下流で、ブレーキおよびオーバーラップ手段は、負の圧力下で維持し吸収ボックス１６で開始し、ボックスの上部の壁は吸収の開口部が取り付けられ、コンベアの平面下をわずかな距離で平行に実行する。負の圧力はシートの後部の端部を吸収し、シートを下方に偏向する。次に、ラインでは、シートがスタック６上に置かれる、より遅い積層速度で実行する、より低いコンベアベルトである。シートがブレーキを掛けられた場合、迅速に移動する続くシートの前方の端部は、ブレーキが掛けられたシートの後部の端部上に摺動する。これは、遅い積層速度で低いコンベアベルト１７上でさらに伝達される、オーバーラップするシートの流れを形成する。
【００１５】
前述の段階においてシートにブレーキを掛ける一方で、高速の上部のコンベアベルト１４から下部のコンベアベルト１７向かって下方に高速移動するシートをプレスするために、上部のベルト１４間の下部のコンベアベルト１３の入り口側の偏向ローラー１８の後ろに、共有軸２１上の周囲に沿って下方へ面している、突出して回転し、ブレーキをかけるローラーが存在する。図３は、ブレーキローラー１９の拡大した断面図を示す。
【００１６】
各ブレーキローラー２０は、共有の回転軸２１に取り付けられた円筒状の基部要素２０から構成される。放射状に突出するラメラ２２は、基部要素２０に付加された弾性物質からなり、ラメラ２２は互いから離れており、基部要素２０に関して共軸である円筒状の包絡面で終了する。好ましくは、ラメラ２２は、軸のスリットが弾性物質からなる中空シリンダの周囲に沿って切断されるように成される。本実施態様において、中空シリンダは約２２０ｍｍの外径を有し、スリットは約２０ｍｍの深さを備えて成される。
【００１７】
好ましくは、図３から分かるように、ラメラ２２はシート２４の移動方向２３に対してわずかに傾く。実施態様において、傾斜角度は、放射部に関して約２０°である。ラメラ２２の端部は、それらの端部の表面が、本質的に共有した円筒状の包絡面を構成するように切り取られる。
【００１８】
ラメラ２２は、弾性で高い耐磨耗性物質からなる。好ましくは、ラメラ２２は、弾力性だけでなく、幾らかの質量圧縮性である、多数の孔を備える多孔質のプラスチック物質からなる。好ましくは、泡の手段により、特にポリウレタンである多孔質のエラストマーからなる。
【００１９】
作動する幅にわたって、ラメラ２２が共有した円筒状の包絡面で終了する、つまり同じ放射位置を有する、回転軸２１上で互いに離れた距離で数多の同一に設計されたブレーキローラー１９がある。
【００２０】
ブレーキローラー１９の形態により、前方のシート端部で入り込むシート２４は、シートの運動エネルギーがラメラ２２に移動されるので、ブレーキが掛けられる。弾力性のラメラ２２は、後ろに向かってプレスされ、偏向により曲がる。前述の段階において、偏向距離はシート２４のブレーキ距離に対応する。圧縮性物質がラメラ２２において使用される場合、同時に、ブレーキを掛けるエネルギーの一部は変形エネルギーに変換される。ブレーキローラー１９の効果的な周辺速度は、下部のコンベアベルト１７上で水平に移動される下部の遅いシート２４の伝達速度とほぼ同等になるまで、シート２４にブレーキを掛ける間に減速される。ブレーキがゆっくりと掛けられるので、衝突およびシートの前方端部のマーキングは回避される。
【００２１】
ラメラ２２の端部でラメラを切り取ることは、その真下にある遅いシート２４に対して次のシート２４ができるだけ遅くプレスされることを意味する。同時に、ラメラ２２は、ラメラ２２が湾曲するので、シート２４をほんのわずかだけ下方にプレスし、その結果として曲がることができる。従来の段階と比較して、先行するシート２４に対して続くシート２４をプレスする間、ブレーキは、未だに存在する相対的な速度だけに掛けられる。シートの表面上のマーキングが回避されるように、プレスすることはほんのわずかなプレス力で成される。ブレーキローラー１９が回転するので、ラメラ２２がシート２４から上げられた後、ラメラ２２はすぐにはね返る。

[0001]
The present invention relates to a device for turning a roll of material, in particular a roll of paper or cardboard, which device is provided with turning means consisting of two blade drums fitted with transverse blades, further downstream from the turning means A sheet transporting means having a brake means provided with a brake roller is provided.
[Background]
[0002]
The turning device is arranged following a stack which is known to have a sheet transport means for turning a roll of paper or cardboard to produce individual sheets, located downstream from the turning means, and a brake roller And brake means. When a brake is applied to the seat, the leading edge of the subsequent seat that has not been braked slides on the rear end of the braked seat. This creates a flow of overlapping sheets that are subsequently laminated by the laminating means. The aforementioned general type of turning means is described in German Patent No. 19945114.
[0003]
When the sheet is pressed downward when the brake roller guides using a known brake means, the sheet flowing at high speed is braked. Therefore, the brake is already applied and the seat becomes slower. Due to the aforementioned relative movement between the two sheets in the braking phase, a marking is made on the surface if the slow sheet of paper or cardboard is of a delicate type.
DISCLOSURE OF THE INVENTION
[Problems to be solved by the invention]
[0004]
Accordingly, the present invention aims to improve a general type of sheet turning device in such a way as to avoid marking on the sheet even if the paper or cardboard is of a delicate type.
[Means for Solving the Problems]
[0005]
This object is achieved in that the brake roller is composed of a cylindrical base element to which radially projecting lamellae of elastic material are added spaced apart from one another along the circumference. The aforementioned lamella stops at a cylindrical envelope that is coaxial with the base element.
[0006]
Due to the form of the brake roller with the radially projecting lamella, the seat is braked with the kinetic energy of the seat moving significantly to the lamella. The elastic lamella deflects back and bends. Thereby, the deflection distance is the brake distance of the seat. At this stage, as a result of pressing the sheet against the lamella, the effective peripheral speed of the brake roller almost perfectly matches the transmission speed of the slower sheet. Only after the faster sheet is effectively braked is it pressed against the preceding sheet.
[0007]
The dependent claims include preferred embodiments of the brake roller according to the invention because it is particularly useful.
[0008]
The accompanying drawings serve to illustrate the invention with reference to embodiments depicted in a simple manner.
BEST MODE FOR CARRYING OUT THE INVENTION
[0009]
The apparatus shown in the general view of FIG. 1 serves to make a sheet of paper or cardboard from a continuously fed roll 1. Subsequent components are arranged continuously in the direction of movement of one turn / sheet (from left to right in the figure).
[0010]
Means 2 for cutting vertically, cutting means 3 and sheet transport means by sheet formed during turning, wherein the ends of the one turn 1 are cut and optionally the one turn 1 is divided into six individual turns 4 is taken over and braked, thereby forming a stacking means in which overlapping sheet streams are formed and the sheets are placed on a stack 6 based on pallets.
[0011]
In a known manner, the turning means 3 usually consists of two blade drums 8, one of which is mounted on the other with one transverse blade attached by means of the sheet passing through and the roll 1 cut. It consists of nine.
[0012]
The sheet transport means 4 is located directly behind the turning means 3 and is shown in the enlarged view of FIG. The sheet transport means takes over the beginning of the roll produced by the turnover and snaps during the turnover to accelerate further transport of the sheet produced by the turnover to create a gap between the two sheets. It includes an element that brakes the sheet so as to form a flow that holds the tension roll and overlaps the sheet fed to the laminating means 5 at a reduced transport speed.
[0013]
The sheet transport means 4 starts with a fast lower conveyor belt 13 associated with the upper catch roller 12. The catch roller 12 is a deflecting roller on the entrance side of the rapidly rotating upper conveyor belt 14 which is composed of individual parallel belts at the same time and is driven at a speed higher than the speed of the incoming roll 1. Together with the catch roller 12, the lower conveyor belt 13 takes over the beginning of the incoming roll and forms a nip. The conveyor belt 13 is driven at the rising speed of the upper conveyor belt 14. Thus, the sheet produced by cutting is transported at a further increased speed.
[0014]
Downstream from the seat lock 15, the brake and overlap means are maintained under negative pressure and start at the absorption box 16, the upper wall of the box is fitted with an absorption opening, and a small distance below the plane of the conveyor Run in parallel. Negative pressure absorbs the rear edge of the sheet and deflects the sheet downward. Next, in the line is a lower conveyor belt that runs at a slower lamination speed where the sheets are placed on the stack 6. When the seat is braked, the forward end of the following seat, which moves quickly, slides over the rear end of the braked seat. This creates an overlapping sheet stream that is further transmitted on the lower conveyor belt 17 at a slow lamination speed.
[0015]
The lower conveyor belt 13 between the upper belts 14 is pressed in order to press the sheets that move at a high speed downward from the high-speed upper conveyor belt 14 toward the lower conveyor belt 17 while braking the sheets in the foregoing stage. Behind the deflection roller 18 on the entrance side of the slab, there is a roller that projects downwards and applies a brake, facing downward along the circumference on the common shaft 21. FIG. 3 shows an enlarged cross-sectional view of the brake roller 19.
[0016]
Each brake roller 20 is composed of a cylindrical base element 20 attached to a common rotating shaft 21. The radially projecting lamellas 22 are made of an elastic material added to the base element 20, the lamellas 22 being separated from each other and ending with a cylindrical envelope surface that is coaxial with respect to the base element 20. Preferably, the lamella 22 is configured such that the axial slit is cut along the circumference of a hollow cylinder made of an elastic material. In this embodiment, the hollow cylinder has an outer diameter of about 220 mm and the slit is formed with a depth of about 20 mm.
[0017]
Preferably, as can be seen from FIG. 3, the lamella 22 is slightly inclined with respect to the moving direction 23 of the sheet 24. In an embodiment, the tilt angle is about 20 ° with respect to the radiating portion. The ends of the lamellas 22 are cut so that the surfaces of those ends constitute an essentially shared cylindrical envelope.
[0018]
The lamella 22 is made of an elastic and high wear-resistant material. Preferably, the lamella 22 is made of a porous plastic material with a large number of pores that is not only resilient, but also some mass compressible. Preferably, it consists of a porous elastomer by foam means, in particular polyurethane.
[0019]
There are a number of identically designed brake rollers 19 at a distance away from each other on the rotary shaft 21, ending with a cylindrical envelope shared by the lamella 22 over the working width, ie having the same radial position.
[0020]
Due to the form of the brake roller 19, the seat 24 entering at the front end of the seat is braked because the kinetic energy of the seat is moved to the lamella 22. The elastic lamella 22 is pressed backward and bends due to deflection. In the aforementioned stage, the deflection distance corresponds to the brake distance of the seat 24. When a compressible material is used in the lamella 22, at the same time, part of the braking energy is converted into deformation energy. The effective peripheral speed of the brake roller 19 is decelerated while braking the sheet 24 until it is approximately equal to the transmission speed of the lower slow sheet 24 that is moved horizontally on the lower conveyor belt 17. Since the brakes are applied slowly, collisions and marking of the front edge of the seat are avoided.
[0021]
Cutting the lamella at the end of the lamella 22 means that the next sheet 24 is pressed as late as possible against the slow sheet 24 just below it. At the same time, the lamella 22 can be bent slightly as a result of the sheet 24 being pressed down slightly as the lamella 22 is curved. Compared to the conventional stage, while pressing the succeeding sheet 24 against the preceding sheet 24, the brake is only applied to the relative speed still present. Pressing is done with very little pressing force so that marking on the surface of the sheet is avoided. Since the brake roller 19 rotates, the lamella 22 rebounds immediately after the lamella 22 is lifted from the seat 24.
